Item Comparative Findings Between Ga-68-PSMA and F-18-FDG PET/CT for Hepatocellular Carcinoma(2020) Erhamamci, Seval; Aslan, Nesrin; 0000-0001-5016-4650; 33094578We have reported here the case of a 69-year-old man who presented with spinal cord compression due to bone metastases as the first manifestation of hepatocellular carcinoma (HCC). For the initial staging, the patient underwent F-18-fluorodeoxyglucose (FDG) positron emission tomography/computerized tomography (PET/CT) imaging, which demonstrated mild F-18-FDG uptake in the multiple expansile osteolytic bone lesions, but no remarkable atypical F-18-FDG uptake in the liver lesion on low-doses CT. An additional PET/CT scan was performed to evaluate the prostate-specific membrane antigen (PSMA) expression, which has recently been reported to be a potential biological marker in a variety of tumors including HCC. High PSMA uptake was recorded in both the metastatic bone lesions and the primary liver lesion/tumor by the Ga-68-PSMA PET/CT.Item F-18-FDG PET/CT Imaging in an Unusual Case of Cutaneous Melanoma Arising From Congenital Melanocytic Nevus in a Two-year-old Girl(2021) Erhamamci, Seval; Reyhan, Mehmet; Bal, Nebil; Torun, Nese; Yapar, Ali Fuat; 0000-0001-5016-4650; 0000-0001-8550-3368; 34082516; AAJ-5242-2021
